Answer :
Final answer:
To add the given polynomials, combine the like terms by adding the coefficients of the terms with the same degree of x. The final result is 7x⁶ - 3x⁵ + 2x³ - x² + 4x.
Explanation:
To add the given polynomials, simply combine the like terms. Start by adding the coefficients of the terms with the same degree of x. For example, 3x⁵ - 5x⁵ gives -2x⁵. Then, combine the coefficients of the terms with x³, x², and x. The final result is 7x⁶ - 3x⁵ + 2x³ - x² + 4x.
